Description: In order to improve the efficiency of selecting talents, the Chicheng police specially developed a test system - the true detection system. As a tester, you need to complete the cracking of the case under the rules of the system. The cracking process of the case is very similar to the real police case. The cases in the system are all actually happened in Chicheng and are stored in the form of key clues. You need to constantly find new clues by looking at the information and fragment the clues. The content pieced together the completed case in your mind and reasoned out the course of the case. As long as you answer the correct questions about the case in the system, you can even crack a case. After you have solved all the cases, Chicheng police will give your final evaluation based on the detection points and your performance.
